More Fortran compiler that supports WebAssembly?

I have a scientific simulator written in Fortran 90/95. It has more than 200.000 lines of codes and I am trying not to recode it with C++.

I would like that other people could run this simulator without installing Fortran or the simulator, directly on the Web.

I know this can be done with C++ through Emscripten and WebAssembly. Or maybe with Fortran 77 converting the code to C with Emscripten and then using WebAssembly.

But, is there some Fortran 90/95 compiler that supports WebAssembly? Is Flang available to do that? Are there some examples? If not, will it be available? when?
